Tool'lwhmn'itnwgcomem:

Be it known that I, Enwanp C. Gnnvnn, a citizen of the United States of America, and resident of Cincinnati, Hamilton county, State of Ohio, have invented certain new and useful Improvements in Garment-Pressing Machines, of which the following is a specification.

My invention relates to garment pressing machines, and particularly to the type 0 machine in which the garment issimultaneously moistened and pressed.

1 An object of this invention is to produce I a pressing machine in which means are employed for supplying v eated steam to the garment, during the pressing operation.

A further object is to produce a boiler provided with improved means for generating live and super-heated steam, and for supplyingl the steam so, generated to the pressing ead of the pressin machine. I

in contra-distinction to super-heated steam, and mean by it Wet or' saturated steam, which has not been super-heated.

A further object is to produce a pressure head for pressing machines, m which 1m proved means are employed for distributing the steam or heating fluid over the pressing surface of the-head.

These and other objects I attain in a machine embodying the features herein described and illustrated.

In the drawings accompanying this application and forming a part thereof, Figure 1 isa' side elevatlon of an embodiment of my invention and discloses a pressing ma-- chine in connection with .an improved boiler; Fig. 2 is a plan view, a portion-being broken away, and shown in sect-ion, of a pressing head embodying my invention. Fig. 3 1s a plan view, showing the underside of the pressing head shown in Fig. 2.

The diflusing screen and cloth covering for the screen are removed in Fig. 3. Fig. 4 is an elevation of-an improved boiler, which forms a' detail of my invention. A portion of the boiler casing is shown broken away for convenience of 1 lustration.- Fi 5 and 6 are sectional views of a portion 0 piping, which forms a detail of my invention. Fig. 7 isa section along the'line 77 of Fig. 2, but with the steam .pipe and admission valve shown in place. Fig. 8 is a section along the line 88 of Fig. 2.

either live or snper- I 9 is a plan view ofa modified construction of a pressing head, and forms an embodiment-of my invention. Fig. 10 is an inverted plan view of the head shown in Fig. 9. Fi '11 is a section along section alon the line 12-12 of Fig. 9.

' In the pressin machine, which consists of a pressmg hea 13, a cooperating pressing block 14, a steam gleneratin apparatus 15, for delivering bot utilizing the excess of' heat delivered to the boiler.

The pressing head 13 and the block 14; are mounted on a frame 17, the block 14 being secured to a work table 18. The pressin head 13 is of the usual form and is provide with a steam deliver passage 19, extendin centrally the entire ength of the head and communicating with an admission port 20, through a branch passage 21. Delivery'apertures or slots 22 are formed-in the head 13, along the passage 19, and'are adapted to deliver steam to the pressing surface ofthe head. A series of transversely extending ridges 23 are formed on the head, for the purpose of aiding in distributing the steam over the pressing surface. The diffusing 9 screen 24; is secured to the pressure head an is located on the rid es 23 above the channels 25, which exten laterally on each side of the passage 19 and communicate with the series of \around the assage 19. This chamber is adapted to supplied with super-heated steam through the inlet port28, A port 29 also communicates 'with the chamber .27 and tion from the chamber.

The steam illustrated in ig-4, consists of a cylindrical tank or generating chamber30, a gas burner 31 located below the tank, super-heating coils 32 located between the burner and the tank, and a casing 33 which incloses the rawings, I have illustrated a live an super-heated steam to the pressing head, and a feed water heater 16 slots 22. The ridges 23 are slotted. at 26 on each side of the slots 22, to form adthe head 13, adjacent tothe ridges 23'and' is adapted to deliver the water of condense the line 1111 of Flg. 9 and Fig. 12 a1,

:Fgeneratmg apparatus 15, as

burner, the tank, the super-heating coils and the feed water heater 16. The casmg is provided at its top with a vent port 34 for the vfumes, which may be connected with a' vent pipe. The gas burner is of any suitable construction and may receive gas from any suitable source. The super-heating coils 32 communicate with the upper end of the tank 30,

vided to permit the position. Wet or saturated steam is delivered to the through piping 35, and deliver super-heated steam through piping 36. The piping 36 connects with t e port 28 of the heating chamber 27 in the pressing head. Suitable connections and joints are,'of course,;'propressing head to be moved from its operative to its inoperative may be cut off, and super-heated steam dethe valves in delivering live steam,

the pi to be moved to an livered thereto.

In Fig. 5 l have illustrated the position of through ing 37, to the passage 19, and superheate steam through the piping 36 to the heatin chamber 27.

, In ig. 6 I have illustrated the position of the valves in delivering super-heated steam .tov both the passage 19 and the chamber 27.

The valve-39 is turned to 'cl'osedirect communication with the tank 30, and to put the passage 19'into connection with the piping 36, through the short pipe 40. The valve 38 is turned so that the steam delivered from the super-heater is divided into two streams,

which continues through the pipin 36, and the other of which is delivered throu h the pipe 40 and a portion of the pi ing 3 to the passage 19. The piping 3 like the pipin 36, .is'provided with'suitable connections, w ich ermit the pressing head (i from the operative and inoperative positions. A whistle valve, or

an othersultable type of valve, 41 is provi ed in the piping 37, convenient. to the hand of the operator, and is adapted to shut off the supipfliy of steam, through the passage 19, to the 1 u be feed water heater 16 is supported by the tank 30, within the casing 33, and is ele-' vated above the tank by means of brackets 43. This construction permits the tank to be subjected on all sides to the heat and .hot'

fumes within the casin 33. The feedwater is delivered to the ta 30 through piping which communicates with a port 44, rovided in the heater, and a port 45, provided moves the pressing head 13 to head. The remainder of the o pressing is similarto that described above.

sing screen 24, when the press-' in head is in the inoperative position.

in the tank30. The temperature of the feed water at the time of dehvery .to thetank is practically that of thewa'ter' in' the tank,

An injector pump 46 is located on' the 'frame 17 of the pressing machine, and is adapted to force water from any suitable source into the boiler heater.

The operation of the apparatus is as follows: When itis' desired to deliver saturated steam to thecloth to be pressed, the valves 38 and 39 are turned, as shown in Fig. 5. This delivers super-heated steam to the heating chamber 27, for thepurpose of heating the pressing head and maintainng the temperature of the steam delivered through the slots 22 to the difiusing screen, and through the screen to the cloth to be pressed. After the garment or cloth is in place on the pressing block 14, the operator position by means of a handle 50 and then holdsthe head in position by means of a foot lever47,

while the valve 41 is, opened, to deliver steam to the garment. When-pressure is removed from the lever 47, the head is raised to the inoperative position, by means of a coiled spring 48,'the flow of steam throulgh the pipe 37 being shut ofi when the va ve 41 is released. If, for the purpose of renovating, it is. desired to deliver su r-heated steam to the cloth or garment to pressed, the valves 38 and 39 are turned to the position shown in'Fig. 6, and super-heated steam is delivered both to the heating chamber 27 and the. pressing surface of the pressing ration of In F1gs 9,10, 11 and 12, I haVe'shoWn a modified form of pressing head. The heating chamber 27, to which super-heated steam is delivered, .is replaced in the modification by .a'chamber 49, in which a gas burner 50 is located. The gas burner is of the Bunsen type and consists of two long perforated pipes, which extend alongthe length, of the pressing head and are located on each side of the steam delivery chamber 19. The perforations in the pipes are so arran d that the flames will be projected on.to t e wallsof the chamber 49, adjacent to the rid es 23 and around the passage 19. ,With t is arrangement, the temperature of the steam delivered by the passage 19 ismaintained and the pressing headis heated. The chamber 49 may be mclosed by a strip of sheetiron secured to the prewng head, or in an other suitable manner.
